Based on the embodiment of the present invention, the drive shaft on the opening/closing latch side is configured such that the drive shaft and the polar opening/closing shaft are brought into engagement when these shafts are moved while keeping their axes parallel to each other in the blocking position. A particularly easily implemented engagement of the shaft and the polar switching shaft is obtained. For this purpose, in particular, the end faces of the drive shaft and the pole opening and closing shaft on the side of the opening/closing latch can be provided with joints in the form of wooden grooves and tongues, in which case in the longitudinal direction of these joints, in the blocking position, Equivalent to the direction of movement of the support frame when installing the opening/closing latch into the case. This facilitates compensation for tolerances in the axial direction of the shaft. Furthermore, experience has shown that even small angular errors can be compensated well if the joint parts are properly designed.

に添え付け可能であることにより実施できる。 By providing the drive shaft on the opening/closing latch side with joint portions for pole opening/closing shafts at both ends, the number of current paths of the circuit breaker can be increased very easily. In this case, a switching shaft of a separate switching pole can be connected to the free end of the drive shaft, for example in order to convert a normally three-pole circuit breaker into a four-pole circuit breaker. This addition of a fourth pole to a normally three-pole circuit breaker means that the case of the circuit breaker has a removable area on the side of the switching latch opposite the pole current path for entry to the drive shaft of the switching latch. This can be implemented in that a single pole with its own pole opening/closing axis can be attached to the case at the same time as it is connected to the drive shaft.

能である。 The driving shaft on the opening/closing latch side has the responsibility of transmitting the driving force prepared, for example, by a spring and a toggle lever installed above the dead center, in the form of a rotary movement on the pole opening/closing shaft, as is well known. This requires good support of the drive shaft on the support frame of the opening/closing latch, and at the same time the coupling element must be in an advantageous position for engagement with the pole opening/closing shaft. In principle, these requirements can be met by a drive shaft with a sufficiently large diameter, but then the bearing hole of the support frame must have a sufficiently large diameter, which is desirable for various reasons. do not have. In contrast, in an embodiment according to the invention, the support frame of the opening/closing latch has a separate ear with a bearing hole, a central shaft body with a protruding leg serving to guide the driving force, and a joint part. The drive shaft is provided with a bridge-shaped additional part that wraps around the free end of the ear part of the support frame as a connecting part between the crosspiece and the shaft body, and this crosspiece starts from the center of the drive shaft and extends approximately at the height of the additional part. It is configured to extend across. In this embodiment, a simple cylindrical pin, which engages in the bearing hole of the isolated ear, is sufficient as a support part for the drive shaft. The bearing characteristics and workability of this configuration are good. Furthermore, the crosspiece used for the connection is located outside the support frame in such a position that it does not cause any problems when connecting the polar switching shaft with the corresponding mating part. Such a drive shaft can be manufactured in one piece from metal or plastic.

る。 Next, as an important part of the opening/closing latch 6,
The glyph support frame 35 will be explained based on FIGS. 2 and 3. The support frame 35 has legs 36 and 37 of the same length but of different shapes, which are interconnected by a central part 40. As can be seen from FIG. 2, the U-shape is not continuous, but is interrupted in the center by an area in which there are two isolated ears 38 with bearing holes 41 for the drive shafts, which will be described later. . Also legs 36 and 37
is the drive lever 3 whose upper end is shown in FIG.

一方桟５５は支持枠３５の外側に達している。 The opening/closing shafts supported in the holes 41 of the legs 36 and 37 will be explained with reference to FIGS. 4 and 5. As shown in these figures, the drive shaft 50 is an integral part, but is divided into parts corresponding to a plurality of functions. Two legs project from the central shaft body 51, which extend parallel to each other at a slight distance and point in the same direction, but have different lengths. The short leg 52 of the drive shaft 50 is used for the introduction of the drive force and is provided for this purpose with a hole 53 for a hinge pin to which a toggle lever system can be connected, for example. The longer leg 54 is used for operating the auxiliary switch, which opens or closes the contacts in relation to the open and closed position of the circuit breaker. A crosspiece 55 forming a joint portion is additionally formed on the central shaft body 51. As can be seen from the figure, the crosspiece 55 covers a bearing hole 56 into which a bearing pin passing through the bearing hole 41 can be inserted. Since the additional portion 57 forms a so-called bridge between the shaft body 51 and the crosspiece 55, the legs 52 and 54 of the drive shaft 50 are placed between the legs 36 and 37 of the support frame 35 when the opening/closing latch 6 is inserted. ,
On the other hand, the crosspiece 55 reaches the outside of the support frame 35.

を備えることもできる。 The extension 57 then wraps around the rounded free end of the ear 38. The asymmetrical position of the crosspiece 55 with respect to the axis of rotation of the drive shaft starting from the shaft center results in a relatively large lever arm length and thus a reliable transmission of torque. The drive shaft 50 shown in FIGS. 4 and 5 can be fabricated as a one-piece piece of metal or plastic of suitable strength. The drive shaft 50 has crosspieces 55 on both sides so that polar opening/closing shafts can be connected to both sides.

is a hollow body with an axial length corresponding to the number of switching contacts to be operated. A double contact lever 62 is rotatably supported on an insulating pin 61 provided inside, and this double contact lever is provided with welded contacts 63 at both ends thereof. This welding contact cooperates with a mating contact which is fixedly arranged in the housing. Each double contact lever 62 is dependent on two torsion springs 64 to provide an initial load to the opening/closing shaft 60. When the opening/closing shaft 60 is operated, the double contact lever 62 is moved until its welding contact 63 comes into contact with a mating contact (not shown). When the opening/closing shaft 60 is further turned, the torsion spring 6 is turned until the necessary contact force is generated.
4 is posted. A groove 65 is provided at one end of the opening/closing shaft 60 in order to start the rotational movement for closing and closing, and this groove is connected to the drive shaft 50 (FIGS. 4 and 5).
It cooperates with the crosspiece 55 on the end face of FIG. 1 in a manner as explained in principle in FIG.
